In the temple of time, Plandes was staying in a spacious and bright room, and before him were Bishop Aslan and Tiya.

"You mean, when the Nicks started the ceremony, the fog had already begun to dissipate?"

Aslan frowned slightly with snow-white eyebrows, and his old face looked a little puzzled.

Planders is a professional ritualist, and here Aslan knows more details.

Planders nodded quickly: "Yes, that madman...Nakes launched the ceremony in advance because he discovered this."

"He thought I was destroying the ceremony, so he was so angry and crazy."

"So what about you?"

Aslan asked directly.

Planders shook his head and said frankly: "The fog of erosion has appeared more and more frequently in recent years. The Secret Words Society is also studying how to remove them, but it has always been a difficult problem."

"That's when someone else is interfering!"

Aslan narrowed his eyes slightly, came to a conclusion, and turned his head to ask Tiya, "Did anyone else enter the fog last night except the Temple Supernatural?"

"We were all concentrated on Rust Water Street at that time, and we didn't know much about other places."

Tiya shook her head gently.

Planders was a little strange and couldn't help asking, "Biography Aslan, why do you think that the fog of erosion fades is artificial?"

Aslan glanced at him and said lightly: "Last Saturday, the erosion fog in the middle of the city had a larger range, and at that time, the erosion fog also disappeared without reason."

Planders was a little surprised when he heard this, and then guessed: "Is it possible... it is because Faralinburg is special?"

Aslan shook his head and pondered: "There has been erosion fog in Falalin Castle before, which was attracted by the extraordinary person's out of control. The temple took the initiative to send people to purify the nightmare, and the fog disappeared."

"But, this erosion mist will not only not be affected by extraordinary power, but will also devour extraordinary power. Can anyone really do this?"

"But no matter what the reason is, this cannot be considered a bad thing for us."

Aslan didn't speak anymore, and his fingers knocked on the handrail rhythmically, thinking silently.

...

Earl's Mansion.

Clint and Rocky's classroom.

When the butler brought the things, it was already an hour later.

Martin looked at the round golden balls in front of him, and his mouth twitched slightly twice.

That is a real golden ball, made of gold!

I don’t know whether it was out of caution in learning, or whether I noticed Martin’s expression, or there was really no other way for a while, butler Shelwin pointed to the Golden Ball and said.

"Teacher Martin, it's really hard to find iron balls, and it's hard to control the weight if the blacksmith is playing. It just so happens that the gold is softer, and each gold bar is exactly one pound."

"This ball is ten pounds, it's one pound."

Gold is very dense, even a ten-pound ball is about the same size as a coconut.

In addition to these two balls, Martin also asked the housekeeper to prepare some wooden balls.

After sighing for two secretly, he took the two students directly to the attic at the top of the manor, opened the window, and began to do the experiment.

It is about ten meters above the ground, which is enough.

The test results are naturally no surprises.

Wooden balls of the same size and golden balls also landed almost at the same time.

When he saw this scene, Clinn widened his eyes and felt a little unbelievable.

Rocky frowned and repeatedly pondered the whereabouts of the two balls just now.

"Did you remember the time to land?" Martin asked by the window in the attic.

Hearing his question, Clin suddenly came to his senses, quickly raised his head and shook the pocket watch in his hand: "About two seconds!"

In this era, there is no such thing as a stopwatch, because it is impossible to use it at all.

Even the clocks made in the Temple of Craftsmen are just walking more accurately.

The clock can only be accurate to seconds, and the time error obtained is very large when the height is not enough.

For example, the two seconds that Clinle reported should be more than one second according to Martin's feeling.

Without accurate time, gravity acceleration cannot be calculated.

However, Martin has a solution.

He connected a very thin thread to the golden ball.

Since the time cannot be accurately measured, the time is unexpected and the time is controlled.

After getting the thin silk, Martin held the pocket watch in his hand and immediately cut off the thread after the golden ball fell for a second!

In this way, the length of the wire is the height of the free fall in one second.

Although there are some artificial operational errors, they can be avoided as much as possible by increasing the number of experiments.

After struggling for at least half an hour, Martin finally got more than ten sets of data.

Martin calculated a little and got an average.

8.02!

This number doesn't mean anything.

Even if it is close to 9.8 on Earth, it is just a coincidence.

Because the unit changes too much.

One yard or one meter here is obviously slightly longer than one meter on the earth.

After collecting the data, just as he was about to go downstairs, the count brought a man to the attic.

Instead of wearing the temple's iconic robe, he was dressed in casual clothes.

He is in his early thirties and looks very capable, with his black hair neatly combed, giving people a meticulous feeling.

"Teacher Martin, this is Deacon Gress." The Earl took the lead in introducing the visitor to Martin.

"Hello, Deacon Gress."

Martin nodded slightly, greeted him with a smile, showing the enthusiasm and respect he deserved in his identity.

Gries seemed very interested in Martin's experiment, with a smile on his face and a friendly tone.

"Teacher Martin, I have also watched the experiment process you just now. It's very interesting. Are you calculating what you are doing?"

Martin nodded and said truthfully: "Gratio acceleration."

This is nothing shameful, and the gentleman in front of him may not be able to understand the meaning of the word.

"Graining acceleration..."

Gress's eyes lit up, as if she had thought of something, and asked again, "Teacher Martin, can I listen to your class?"

Of course, Martin would not refuse and nodded immediately to agree.

Multiple people should be able to get more experience points!

Back in the teaching room, Martin first gave Glescoop the concept of acceleration.

He understood the uniform speed and uniform acceleration movement very quickly.

Then, Martin began to deduce the formula for gravity acceleration.

Martin wrote on paper the process of calculating the acceleration of gravity.

This is pure mathematical calculation.

Soon, based on more than ten experimental data of the golden ball and the wooden ball, the respective gravity accelerations were calculated.

8.12,8.05.

The difference is very small, and in their rough experiments, such accurate data are completely acceptable.

"So for gold and wooden balls of the same size, their whereabouts are almost exactly the same because their gravity acceleration is consistent."

Martin gives the final conclusion.

"But they obviously have different weights?" Clinn was still very confused.

Martin smiled slightly. Although he couldn't understand it for a while, at Clin's age, understanding how to think is the most important thing.

"Yes, that means the gravity acceleration during falling is not affected by the weight of the object. Now, the question is back to what I have taught you for the first time."

"Why do objects move? Or, have you ever thought about why objects will definitely fall!"

Clinn's expression became confused, and she frowned and asked, "Yes, why is she falling?"

Gress, who was standing beside her, also frowned, thinking about the questions raised by Martin.

In fact, the conclusion is very simple. Rocky, who is extremely talented and has great interest in this area, quickly answered it.
